Even though Mukul Roy spoke about why he left the party there was no clarity on whether he would be joining any other party or start a party of his own

Mr Ghosh, an accused in the Saradha scam, said he had submitted a petition to the CBI seeking joint interrogation with Roy.

Congress leader Somen Mitra on Thursday expressed doubts about the motive behind Mukul Roy's resignation from the Trinamool Congress and claimed there could be "a secret understanding" between him and the top party leadership to hide "wrongdoings" of some leaders. "This is misleading", said Ghosh, who spent over two years in jail in connection with the Saradha case.

Claiming Roy's allegations of dynasty politics in Trinamool Congress to be true, Ghosh said it is unjust that a leader like him who worked so hard for the party had to leave in this way.

"This happened after (Congress vice-president) Rahul Gandhi refused to accept him into his party".

He recalled that he was one of the signatories when the Election Commission had recognised the TMC as a political party.

"Bypolls to a couple of Assembly seats in Bengal will be held in November". Also according to some of their leaders he has built up a good rapport with some BJP leaders.

Later, when Roy was asked in Delhi to comment on Ghosh's remarks, he said he would not react to the "ramblings" of a "frustrated mind". "I would like to give my suggestions so that elections in Bengal are held like they were in 2009 and 2011", he said.
